[OSM-dev] Whitespace in tag-keys

I did not find explicit informations about this issue in the wiki so I'm
wondering whether whitespace in keys is a "should not" or a "must not".

What's the recommended action if one detects tags like eg.

  http://www.openstreetmap.org/browse/node/275671906 (k="is in")
  http://www.openstreetmap.org/browse/node/447654517 (k=" type")
  http://www.openstreetmap.org/browse/way/38170057 (k="  " v="residential")
  http://www.openstreetmap.org/browse/way/39240565 (k="" v="Gweyn Hughs Road")

A second question about ways/relations with less than two nodes/members:
Is there any reason for these? Eg.


Thanks in advance.
